Performance Profile Summary

Date / Time: 05/15/03 15:17:05

Performance profiles for different objective value tolerances. The profile utility compares solver outcomes of any number of given solvers (up to 8) over a model test set. The tool is described in detail at http://www.gamsworld.org/performance/pprofile.htm.

A solver is considered feasible or optimal, if it has the proper model and solver return codes and the relative objective value error is within n % of the best possible solution. If the best found objective value is 0, then the absolute objective value error is used.

The following relative objective value tolerances are used:

Only best objective value (i.e. 0 % of best solution found. Actual tolerance used is 1e-5 using relative error)
Relative objective value error is within 0.01.
Relative objective value error is within 0.02.
Relative objective value error is within 0.05.
Relative objective value error is within 0.10.
Relative objective value error is within 0.50.
No objective value tolerance, i.e. we do not check if obj is best found.
